OBJECTIVES: Campylobacter jejuni is an unusual cause of myocarditis and could easily be missed. METHODS: We describe a case of a 25 year old man, who presented with 3 day history of vomiting and diarrhoea, followed by chest pain and significant high sensitive troponin rise. RESULTS: The patient's profuse diarrhoea was accompanied by raised inflammatory markers, electrocardiogram changes and evidence of cardiomyopathy on transthoracic echocardiogram...

Enteroviruses are RNA viruses that are responsible for both mild gastroenteritis and mild respiratory illnesses as well as debilitating diseases such as meningitis and myocarditis. The disease burden of enteroviruses in the United States is difficult to assess because most infections are not recorded. Since infected individuals shed enterovirus in feces and urine, surveillance of municipal wastewater can reveal the diversity of enteroviruses circulating in human populations. Therefore, monthly municipal wastewater samples were collected for 1 year and enteroviruses were quantified by reverse transcriptase quantitative PCR and identified by next-generation, high-throughput sequencing...

Acute influenza-associated myocarditis varies in clinical severity ranging between asymptomatic and fulminant varieties. The most severe cases can result in impaired cardiac function‑associated mortality; however, the mechanism underlying the development of viral myocarditis has yet to be fully elucidated. The present study investigated the apoptosis induced in H9C2 cardiomyocytes by infection with the H1N1pdm2009 virus. The H9C2 cells were transfected with nucleoprotein (NP)‑specific short hairpin (sh) RNA, and viral replication was re‑evaluated in H9C2 cells infected with the H1N1pdm2009 virus, as was the apoptosis induced by the virus...

Canine parvovirus-2 (CPV-2) is nearly indistinguishable from feline panleukopenia virus (FPV) and is a well-known cause of viral myocarditis in young puppies; however, it is not known whether either FPV or CPV-2 naturally infects feline cardiomyocytes and causes myocarditis. Endomyocarditis (EMC) and left ventricular endomyocardial fibrosis (LVEF), clinically known as "endomyocardial restrictive cardiomyopathy," are important feline heart diseases suspected to have an infectious etiology. A continuum is suggested with EMC representing the acute reaction to an unknown infectious agent and LVEF the chronic manifestation of repair...

BACKGROUND/AIMS: Mitochondrial DNA (mtDNA), acting as a newly found 'danger-associated molecular patterns' (DAMPs), is released into circulation upon tissue injury and performs as a considerable activator of inflammation and immune response. However, the role of circulating mtDNA in experimental autoimmune myocarditis (EAM) as well as Toll like receptor4 (TLR4) mediated cardiac inflammation and injury remains unknown. METHODS: A model of EAM was established in BALB/c mice by immunization with porcine cardiac myosin...

BACKGROUND: Late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR) has been recommended to distinguish Tako-tsubo cardiomyopathy (TTC) from either acute myocardial infarction or myocarditis. METHOD: 44 consecutive patients with confirmed Mayo Clinic criteria for TTC underwent CMR imaging at 1.5 Tesla during the acute phase. 10 patients who had CMRI to exclude scar related ventricular tachycardia, and had negative studies, were used as negative controls...

A 5-month-old female captive Malayan tapir (Tapirus indicus) died suddenly without preceding symptoms. Gross necropsy revealed numerous white circular and linear foci in the myocard. Differential diagnosis all turned out negative, except for encephalomyocarditis virus. Histopathology revealed mineralisation of myocardial cells and interstitial infiltration of lymphocytes, plasma cells and less neutrophils. Encephalomyocarditis virus was detected by PCR. Although encephalomyocarditis virus occurs in many mammals, this is the first published description of this virus in a Malayan tapir...

Light-sheet fluorescence microscopy (LSFM), in combination with chemical clearing protocols, has become the gold standard for analyzing fluorescently labelled structures in large biological specimens, and is down to cellular resolution. Meanwhile, the constant refinement of underlying protocols and the enhanced availability of specialized commercial systems enable us to investigate the microstructure of whole mouse organs and even allow for the characterization of cellular behavior in various live-cell imaging approaches...

Theiler's murine encephalomyelitis virus (TMEV) infection has been used as a viral model for multiple sclerosis (MS), as TMEV can induce chronic inflammatory demyelinating lesions with viral persistence in the spinal cord of SJL/J mice. In contrast, when C57BL/6 mice are infected with TMEV, the mice can clear the virus from the central nervous system (CNS), without viral persistence or demyelination, but develop seizures and hippocampal sclerosis, which has been used as a viral model for seizures/epilepsy. In the two TMEV-induced CNS disease models, not only viral infection, but also immune responses contribute to the pathogenesis...

BACKGROUND: Acute myocarditis (AM) often involves the left ventricular (LV) subepicardium that might be displayed by cardiac magnetic resonance even late after the acute phase. In the absence of global or regional LV dysfunction, conventional transthoracic echocardiography (TTE) does not accurately identify tissue sequelae of AM. We sought to evaluate the diagnostic value of two-dimensional (2D) and three-dimensional (3D) speckle-tracking echocardiography to identify patients with a history of AM with preserved LV ejection fraction (LVEF)...

Hypereosinophilia may be due to several aetiologies. Cardiac complications are not uncommon, whatever the causes. Clinical presentations of hypereosinophilic cardiac diseases may vary widely from asymptomatic form to fatal necrotic myocarditis or irreversible restrictive cardiomyopathy. As a major cause of morbidity and mortality, diagnosis of cardiac involvement is crucial. Until recently the diagnosis was exclusively based on cardiac biopsy. Nowadays, multimodal cardiac imaging, including echocardiography and cardiac magnetic resonance imaging, is the cornerstone of the diagnosis...

INTRODUCTION: Organ-specific autoimmune diseases are believed to result from immune responses generated against self-antigens specific to each organ. However, when such responses target antigens expressed promiscuously in multiple tissues, then the immune-mediated damage may be wide spread. METHODS: In this report, we describe a mitochondrial protein, branched chain α-ketoacid dehydrogenase kinase (BCKDk ) that can act as a target autoantigen in the development of autoimmune inflammatory reactions in both heart and liver...

Eosinophilic myocarditis (EM) is a rare condition that may result from several heterogeneous eosinophilic diseases, including parasite infection, hypersensitivity reaction, vasculitis, and hypereosinophilic syndrome. Regardless of etiology, the disease may present with various cardiac conditions, such as acute coronary syndrome, heart failure, or arrhythmia. Irreversible endomyocardial fibrosis, which causes restrictive cardiomyopathy, occurs in the late phase of the disease. Early diagnosis and treatment is crucial to prevent disease progression...

IL-17 plays a key role in a variety of autoimmune diseases. Monocyte chemoattractant protein-1 (MCP-1) is involved in the infiltration of mononuclear cells of myocardium in viral myocarditis (VMC). However, the relationship between IL-17 and MCP-1 in myocardial injury remains unclear. In this study, the expression of MCP-1 mRNA and protein in cardiac myocytes were detected with qRT-PCR and ELISA respectively. It was found that IL-17A induced MCP-1 expression in a dose and time dependent manner in cardiac myocytes, which could be blocked by IL-17A and IL-17RA neutralizing antibodies...

Breviscapine is a crude extract of several flavonoids of Erigeron breviscapus (Vant.) Hand.-Mazz., containing more than 85% of scutellarin, which has been traditionally used in China as an activating blood circulation medicine to improve cerebral blood supply. Accumulating evidence from various in vivo and in vitro studies has shown that breviscapine exerts a broad range of cardiovascular pharmacological effects, including vasodilation, protection against ischaemia/reperfusion (I/R), anti-inflammation, anticoagulation, antithrombosis, endothelial protection, myocardial protection, reduction of smooth muscle cell migration and proliferation, anticardiac remodeling, antiarrhythmia, blood lipid reduction, and improvement of erectile dysfunction...

The clinical presentation of acute myocarditis in children may range from asymptomatic to sudden cardiac arrest. This study analyzed the clinical spectrum of acute myocarditis in children to identify factors that could aid primary care physicians to predict the need for extracorporeal membrane oxygenation (ECMO) earlier and consult the pediatric cardiologist promptly. Between October 2011 and September 2016, we retrospectively analyzed 60 patients aged 18 years or younger who were admitted to our pediatric emergency department with a definite diagnosis of acute myocarditis...

Macrophage activation syndrome (MAS) is a rarely reported complication of Kawasaki disease (KD). It must be sought during KD with unusual clinical signs, such as enlargement of the liver or spleen, cytopenia (including thrombocytopenia), and elevated serum triglycerides. Here, we report four cases from a single center. The first is the description of a case of KD occurring in an 11-month-old child 15 days after the occurrence of infectious spondylitis. For the second, acute myocarditis heralded KD in a 5-year-old child...

Background -Previous reports have suggested that despite their dramatic presentation, patients with fulminant myocarditis (FM) might have better outcome than those with acute non-fulminant myocarditis (NFM). In this retrospective study, we report outcome and changes in left ventricular ejection fraction (LVEF) in a large cohort of patients with FM compared with NFM. Methods -The study population consists of 187 consecutive patients admitted between May 2001 and November 2016 with a diagnosis of acute myocarditis (onset of symptoms <1 month) of whom 55 required inotropes and/or mechanical circulatory support (FM) whilst the remaining 132 patients were hemodynamically stable (NFM)...
